Hey, 88 iroc Z 350 with a Borg Warrner 9 bolt rear end, 2:77 disk breaks. It ran out of fluid and i didnt notice untill it started making a grind noise comming from the back. Put gear oil in it and the grinding got alittle quiter but never stopped. eventually it striped out and would not move. Took it to shop and they said that they cannot get a carrer baring for it, they have everything else. im trying to do better than 2:77's like 3:73, but im not sure if its even possible to get the part for it. Also if you have any information on the actuall specs on those rear ends since i've heard that they were not used for long or this setup was rare.
